I solve problems by building things that work in production, not tutorials that run once.

Proof of work:
- URL Shortener + Analytics API — solved click-tracking & traffic analysis (FastAPI, PostgreSQL, JWT, GeoIP)
- E-Commerce Price War Analysis — solved cross-platform price comparison across 156 products (Selenium, Pandas, Plotly, live on Streamlit)
- REST API with JWT Auth — solved secure data access, deployed to production VPS (PostgreSQL, SQLAlchemy)
- Web3 Analytics Telegram Bot — solved fragmented on-chain monitoring with 11 integrated modules, running 24/7 as a systemd service

Stack: Python, FastAPI, PostgreSQL, SQLAlchemy, JWT, Pandas, Plotly, Selenium, Web3.py, Linux/VPS.

Certified: HackerRank Python & SQL (Basic), Kaggle Python.

Looking for: Junior Python Developer / Backend Developer / Data Analyst — remote, full-time or contract. Also open to freelance work.
